AI TUTOR + INSTRUCTOR INSIGHTS
AI support for students. Insight for instructors.
Students get Socratic help while they work, directly within Expert TA. At the same time, instructors gain visibility into the questions students are asking, the misconceptions that are emerging, and where the class may need additional support.
Context-aware support
The Tutor knows the problem the student is working on, so the conversation can stay focused on the work at hand.
Thoughtful guardrails
Guidance is designed to help students reason forward rather than simply reveal answers.
Instructor transparency
Student questions and misconceptions can be organized into useful class-wide trends, giving instructors a clearer view of where students need help.
ONLINE HOMEWORK
Built from the mistakes students actually make.
When thousands of students work a problem, their incorrect answers reveal patterns. Expert TA uses years of student response data to identify common errors, then subject-matter experts write targeted, Socratic feedback for those mistakes.
The result is feedback designed around real student thinking, not just a generic “try again.”
Quality questions
Expert TA provides carefully developed questions designed to assess understanding and support meaningful practice.
Specific feedback for common mistakes
When a student’s response matches a known error pattern, Expert TA can provide guidance written specifically for that mistake.
Guidance that keeps students thinking
Socratic feedback helps students recognize what went wrong and work toward the solution themselves.
AUTHENTIC STUDENT ENGAGEMENT
Designed for authentic student engagement.
Learning leaves a trail.
When students genuinely work through challenging problems, their activity looks different from simply arriving at an answer. They make mistakes, try again, seek help when they need it, and produce patterns of performance that instructors can examine alongside quizzes and exams.
Productive persistence
Students continue making attempts, including when additional attempts carry a cost.
Help-seeking behavior
Students choose to access hints and targeted feedback when they need support, even when that may involve a point deduction.
Meaningful performance patterns
Homework performance shows real variation and can be compared with proctored quiz and exam performance.
Build course materials around the way you teach.
Start with high-quality OER. Rearrange it, combine sources, add your own content, and publish a custom digital textbook for your course.
Edit and reorganize
Change chapters, sections, examples, explanations, and sequence to fit your course.
Combine and import
Bring together OpenStax and other OER with your own PDFs, PowerPoints, Word files, notes, and other instructor materials.
Publish, teach, and keep improving
Your course materials stay editable throughout the semester. Add new examples, links, images, or current developments, and students access the updated version without needing to download a new copy.
Create once. Improve anytime.
RESEARCH + RESULTS
More than data. A culture of learning from it.
Expert TA supports more than 50,000 students each semester across hundreds of institutions. That creates a remarkable body of information about how students learn, but having data and learning from it are two different things. With roots in education research, we use evidence from real student interactions to understand where students struggle, how they respond to feedback, and how we can build better tools to support learning.
That research mindset has shaped Expert TA from the beginning. During our first year of classroom use, we analyzed tens of thousands of student mistakes to identify common patterns, then worked with PhD educators to develop targeted feedback for those mistakes. Our first large-scale classroom study examined how students used that feedback and what happened next.
